Application filed November 3, 1924. Serial No. 747,615.

M i invention relates to improvements in faucets and has special reference to faucets of the hind which are particularly adapted to be opened by use of the 'tumbler which is to be filled, especially with water.

The object of my invention is to provide a durable, easily operable faucet, all of the parts of which are of substantial size and durability and one which even a person unacouainted with its operation thereof could not lielp opening' it at once by the use oi a tumbler to be lille'd.

My faucet, as those usually employed for this purpose, is automatically closed upon the release or withdrawal of 'the tumbler.- A particularly valuable feat-ure of my ini/ention resides in the provision of an auxiliary check valve which automatically closes the faucet upon the failure or removal of the automat-ic flow parts or valve.

In connection with the automatic nieehanisin or devices I provide as an additional convenience a simple means for easily set-sV ting the faucet for continuous flow and which can as easily be released'to bring the auto= matic tumbler operation into effect..

My invention will be more readily understood by reference to the accompanying drawings forming part of this specification and in which z- Figure 1, is a side elevation of e faucet embodying' my invention in a preferred form and shown mounted upon a liquid supply tank re 2. is a vertical central sectional view of the faucet;

Figures 3, l, and 5 are horizontal sections on the lines 3 3, e141, and 5 5 respectively of Figure 2,'

Figure 6, is a. fragmentary horizontal section on the line @Q6 of Figure 2;

Figure 7, is u view" similar to Figure 1 and illustrating a slight modification; A

Figure S, is a sectional View similar to Figure 2 and illustrating a. slight modification of my `invention g and Figure 9, is a horizontal section on the line 9-9 of Figure 8.

In said drawings, 10 illustrates the casing of the faucet. The casing is cylindrical and has an inlet 11 at its top for the admission of the liquid to be delivered. The inlet is connected with a supply tank l2 or other source of supply of liquid under pressure.

with a. central opening 17 in which a delivery nozzle 1S is mounted. The nozzle is provided yvit-h a circun'iferential groove 17 in Milch the inner periphery of the disk 1/1 is held, the connection being such that no leakage occurs at this point.A The delivery tube extehds above' and below the disk, its upper end carries a hood valve member 19 which is secured to the upper end of the tube and has av circumferential shirt 20 which extends down'and is adapted to sent on the dish 14 and prevent the liquid flowing from the' interior of the casing to the delivery tube. The portion of theotube 18 Within the hood 19 is provided with radial holes 21 which connect the central longitudinal opening 22 of the tube with the space beneath the' hood 19. The loiver end of the delivery opening is freelv open. lVhcn 'the faucet is installed and the fluid unL der pressure is admitted tothe casing the pressure forces thehood 19 down and seats its lower ed. upon the disk 14, thus e'fi'ecl` tively shutting olf all flow of liquid from the faucet. To open the faucet for the flow of liquid therefrom it is merely necessari' to force the lower end 23 of the (ileliveriy lube slightly to one sido, thus tippingy the hood 19 and lifting iL o r edge free of the disk at one side, a i own in the dotted lines. As soon as the tube 18 is again released the pressure again seats the hood firmly and stops the flow. I

To assure the firm seating of the 'hood and the closing of the faucet, I preferably provide additional pressure means, in the form of a compression spring 24 seated at its lower end upon the top of the hood and seated at its up per end upon a shoulder 25 provided in the upper part of the casing. VI provide the hood with a spring centering projection 2G to hold the lower end of the spring central and the upper end is centered by a projection 27 on the shoulder 9.5. In the form shown the top 28 of the casing is removable from' the casing, being joined thereto by a threaded connection 29.

Cit

y valve 33 the stem 34 of which er TWithin the top part 28 l provide a trai'isverse wall 8G which forms the shoulder and which is entered into the top part E28 from below, being preferably secured in place by a screw-threaded conne tion 3l. This wall has a central opening 32 within the centering pro jection 2.7 and which connects the interior of the top part 2.8 with the body of the casing. For the purpose of stopping the flow of liquid through the faucet in case it is noceie rv to remove the diaphragm 14, l prei de through the openii rlfhis v usual Greek-cross section providing ample flow passage for liquid. ',ilie head 3o' of the valve 33 extends out over the wall .36 and is provided on its under side with a soft seating ring 36 adapted to seat on a rounded circumferential valve seat 37 when the valve is free to be seated by the fluid pressure, normallv the valve is held free of its seat by a downwardly proj ecting rod 38 which is rigidly secured at its upper end to the valve and is made of such length that its lower end 3E) rests upon the top surface of the projection 26. 'lhe top surface of the projection 26 is provided with a centering depression 39 for receiving and centering the lower end of the stein 38. lt will readily be seen that if the diaphragn'i 14, .were to be removed t ie hood valve 19 would be pushed down by the spring 24 and thus the check valve 33 would be relieved of support and would be immediately seated by the pressure in the upper part of the casing.

Thelower head l5 of the casing is provided with a central opening 40 through which the delivery stem 18 projects and which is cone( or widened out toward tue lower end to permit the free tipping of the stem 18, as hereinbefore described, for opening the faucet.

For conveniently forcing the delivery stem to one side to open the faucet, l provide a stand or support 41 for a tumbler' 42, arranged centrally below the stem 18 and connected thereto by a bracket arm 4;) which rises from the base 4l. at one side so as to permit the ready placement of the tumbler upon the base. The arm 43 extends inwardly at its upper end and has a hub 44 adapted to be clamped tightly upon the stein 18, preferably by a set screw 45. rlhe base 4l is provided with upstanding projections 46, forming a socket within which the bottom of the tumbler 42 is received and by means of which the stem can be readily pushed over by side pressure applied to the tumbler in a readily obvious manner.

lt is sometimes desirable to hold the faucet open for some time, as in filling quite a number of tumblers. For this purpose I provide simple means for forcing' the delivery tube 18 to one side and retaining it there until it is desired to release it. This means, shown in the drawings, consists of a lever 4" pivoted to the bottom of the head l5 and having handle 48 which extends out beyond the edge of the head. The lever is pivoted to th-e head by a pivot 49 near its inner end to swing in a horizontal plane. rlhe lever has a rounded notch 50 at its inner end which is substantially concentric with the lower end of the 'tapered opening 4() so that normally the tippi t nozzle i8 by a tumbler will not be hindered. rhe lever is Tidened out at each side at its inner end, as shown 5l, and each wing is previded v-.fith a rounded notch 52 adapted to be swung around to engage the tube lil and it over. 'lhese notches 52 fit the outer sui of the tube, and once tube is eng d in either thereof itwill remain therein until re leased. rllhe arrangement is such that when the tube is thus engaged it is forced over to one side, sutlicient to open the faucet, as enplained. To retain the lever 47 in its normal central position, l provide a ball 53 with a compression spring 54 above it and adapted to engage in a depression 55 provided in the upper surface of the lever 47. Obviously other depressions 56 can be provided in the lever to be engaged by the ball to hold the lever in faucet open position.

ln Figure 7, l have illustrated a form of casing where the liquid enters directly into the body of the casing instead of into the top as heretofore described, as shown at 57. Obviously in this form the check valve 33 cannot be used.

ln Figures 8 and 9, l have illustrated a modied form of my invention. rilhis modified form is not provided with a tumbler receiver but with a simple lever by which the delivery tube 60 of this form of faucet can be slightly deflected for opening the faucet. As shown, this arrangement comprises an arm 6l secured rigidly at one end to the delivery tube 60 and extending up alongside of the body of the faucet. The free end 62 of the arm 6l, is received between two lugs 63 projecting out from the side of the body of the faucet.

t is obvious that by moving the free end 62 of the arm 6l the delivery tube 60 will be forced out ofits normal posit-ion andthe oiaphragm .distorted as has been described.

l provide a simple means for forcing the free end of the arm 61 out of its normal posi tion and retaining it in faucet open position. This means comprises a hand lever 64, having an end arranged between the lugs 68 and pivotally mounted upon said lugs. The lever 64 has a cam projection 65 which is adapted to engage the free end of the arm 6l and force same outwardly when the lever 64 is swung downwardly, as shown in dotted lines, Figure 6. The projection 65 is preferably arranged to pass centers when it is pulled down, whereby the faucet remains open until the lever 64 is swung up again. l/Vhen the lever 64 is lifted the free end of the arm 6l is forced inwardly by the resiliency of the diaphragm, and t-he cam projection is arranged so that it passes centers on the upward movement of the los lever. By this means the arm 61 retains the lever 64: in its upper or faucet closed position.

The internal construction of the faucet is similar to that already described. The delivery tube is mounted in a rubber-diaphragm 66 which is clamped against the lower open end of the body 67 by head 68 which is screwed onto the body. In this form I also iiiterpose a faucet closing spring 69 between the valve head 7 0 and a partition wall 71.

It is obvious that the tumbler support shown in Figure l could be secured upon the delivery tube 60.

As many modiiications of my invention will readily suggest themselves to one skilled in the art, I do not limit or confine my invention to the specific details of construction and operation herein shown and described. v

I claim In a faucet of the kind described, a discharge tube mounted in a flexible wall, means normally sealing the inner end of the tube and adapted to be opened by inclining the tube out of its normal position, a support rigid with the tube for receiving a vessel to be filled and adapted to be moved from its normal position by sidewise pressure on the vessel to be lilled.

In testimony whereof, I have hereunto set my hand, this 30th day of October, 1924.

RUDOLPH MUELLER.
